Hello. I'm really having a serious problem with my sound device. I'm using a Windows XP Helwett Packard laptop. I recently downloaded Realtek High Definition Audio application and installed it but I saw a yellow exclamation mark on my sound device. I opened its properties only to find a Code 10 error. The driver simply refused to start. What do I do? I've gone to services.msc to enable my Windows Audio. That didn't help. I've even reinstalled over and over. That didn't work. Please help
